srmrr LEVEL.

' Application tied June 1, 1925. serial Nasgaia Y 'My inventionrelateslto an improvement in i spirit levels,` and is particularly applicable to spirit levels employed intrack work on railways. Y

-Levels employedon railway work for leveling up the rails are subjected to rather.

hard usage with tne result that they easily become brokgeii'and out of repair, and it is also an objection that the llevel must belong enoughY to reach from one rail to the other, and in levels of this length, the device easily beccmes'warped and bent.

it is an object of my invention to provide Va level for track work wherein the spirit level'is so mounted that it will not easily be broken or iniured b the war in@ orbend- .l y a ing of the body of the level. Itis also desired to protect the vdevice fromv breaking under shocks or blows, and to maintain the device in alignment under all circumstances.

Referring to the drawing herewith, Fig. 1 .is a top plan view ofa structure embodying my invention.v Fig. 2 is a side view, partly inelevation and partly in vertical section. Fig. 3 is an endV elevation thereof. Fig. 4 is also an end elevation taken from the end oppositeV to the view shown in Fig. 3; and Fig. 5 is a vertical section on the line 5 5 of Fig. 2.

made of wood, or some other light rigid material. ln the embodiment sliownin the drawing, 1 have divided the body into two Y at 2, and held in extended position by means of a latch 3 on the side thereof.- The body of the level is provided with a longitudinal groove, or channel, 4 extending the. full as to include somewhat over {one-half the thickness of a body of the level. At one end of the body of the level I employ ametal` plate 5 which is bent at an angle on its lower end to form a shield 6 covering the lower end of the body. At the endof the body of the level,'the platev 5 extends upwardly to the full thickness of the device.A As shown in Fig. 3, this plate is formed with a notch, or recess, 7 thereon to correspond with the channel 4 in the body of the level. The plate forms a bearing for a crossv pin 8 extending Y transversely of the recess 7 at a point spaced somewhat upwardly from the lower wall of i a rigid body havingV acentral channel lonthe channel. Y Y

Theopposite n end ofthe structure has fattachment of a spring 14. I.

1n order that the device may be easily4 .thereon a similar plate 9 with a lowerangulan portion 10 thereon, and an upwardly eX- tendingeiid portion, which has a central` aperture'll therein to allow the attachment ofv tliegle'vel support. A. transverse rod 12 'eXteIlding across said aperture is curved inf .wardly `to, provide a shortloopl .rforr'tlie The spirit level, shown-at 15, is. mounted upon a plate 16 in any desired manner, either by riveting or brazing, *or other similar means. Theend of the rod 8 iscurvedvabout the rod to form afhinge `1T so that it may-swing thereon. The end plate adjacent the ofvtheplate 16, away from vthephinge thus provided, is attached to a wire 18 which eX- tends longitudinally` of the 4channel 4 and is secured at its other end tothe'spring 14. The wire 18 and the spring 14 are of strong construction, and. l contemplate piano wire or other similar substantial construction. The spring `14 serves to maintain the wire which the spirit level is mounted, willbe always in alignment. j

It will be noted that the hinge 17 and the rod 12 at the opposite end are secured to met-al plates at points spaced equally above the lower'side of the body 1 of the level;

hence when the device is'placed upon the p i V,construction is light and durable, and the length of the device and being of such depth..V

mounting of the level is such that it will withstand ordinary rough usage and be always inaintaiiied'in accurate alignment. It isV also. to be notedthat rthe device is easily portable inthat the latch 3 may be disenf gitudinally thereof, plates :onrsaid body at 18 taut at all times so that the plate 16, upon y each end thereof, a resilient linein said channel secured at each end of saidbody to said end plates, and a spirit level secured rigidly upon said line for the purpose described.

2. In a device of the character described, a longitudinal body of rigid material, said body being in two sections hinged together, end plates on said body, a supporting plate hinged'to oneV ot said end plates, aspring secured to the opposite end plate, and a Wire connecting said supportingr plate and said spring.

3. in a device of the character described,

i) a rigid body having a longitudinal channel 4. In a device of the character described, i

a rigid supporting body, a Wire extending longitudinally therethrough, a supporting plate aty one end of .said Wire, a spirit level on said supporting plate, a spring at'the opposite end of said Wire, and means for connecting said sprin to the ends of said body at points Vspaced equally from the lower side thereof.

Y In testimony whereof l hereunto vaiiiX my .signature this 29th day of May A. D. 1925.
